Answer
Yukine, voiced by Hosoya in the anime series "Noragami," is the main character Yato's shinki. Originally a stray spirit bound to Yato, he initially resents his servitude and frequently clashes with Yato. As the series progresses, Yukine gradually develops a strong bond with Yato and comes to understand his true nature. Hosoya's vocal performance effectively portrays Yukine's complex personality and emotional growth throughout the series.
